Hi, I can’t offer a hiking mate with my current fitness, but a personal log to the Lincoln if you like:

“Charlie’s Pike” literally means my hiking buddy was too clapped out to complete it, so I left him there and met him again on the way down.
I can email it if you have a GPS that can use the track data, and you could easily continue the walk to the peak.
It’s a fairly low risk walk if you find the creek line whether it’s running or not, and stick to that all the way up.
You should have found the creek line around where this track turns brown.
I did make a trip there once, and never found the wreck, or on a correct track any of the time!
Just went up a certain distance through awful scrub, and back down again.
Last time I went I think was 2009. This pic of the wreck is definitely 2009:

You need a reliable 4WD to even get to the Emu Crk campsite, and it doesn’t take much rain to make the drive in/out near impossible.
Unless you’re particularly interested in the wreck, or whatever land beyond that, I don’t rate the nature walk for Superbus highly at all.
